The spectral distribution of light influences microalgae productivity; however, development of photobioreactors has proceeded largely without regard to spectral optimization. Here, we use monochromatic light to quantify the joint influence of path length, culture density, light intensity, and wavelength on...

Digested effluents are usually deprived of the appropriate levels of organic carbon or macro- and micro-nutrients to effectively sustain microalgal growth. In this regard, Parachlorella kessleri was cultivated in an agro-waste digestate supplemented with different glucose concentrations, magnesium and trace...
